Pieces Of Me

It was like there are all these pieces of my life that had fit together before this graduation year. A puzzle with an exact number of pieces and a perfect fit. Somehow, some way, the puzzle had broken apart. And I'm trying to put it back together again, but the pieces had changed their shape & don't fit anymore... There seems to be new pieces to fit in. What are they..? Or is it wasn't even them in the first place...
